A place where you'll find a pretty balanced Civic hybrid article (as well other hybrids) is at http://www.greenhybrid.com/learn/If anyone knows a decent Civic Hybrid forum please let me know....
You may want to try the yahoo civic_hybrid group. http://autos.groups.yahoo.com/group/civic_hybrid/
Try your local dealer and see if you can take one home for a day or two so you can try your route. Before you do though, do some more research on efficient ways to drive it so that you are giving the car a fair chance.
My biggest concern would be the hills, but with the 5-spd you should be able to adjust accordingly if needed.
